Cons

The Polk Audio RTi A1 is a high-performance bookshelf loudspeaker surrounded in one of two options of real wood. One RTi A1 selling point is that it is the same price as similiar vinyl speakers but delivers better sound because it offers black or cherry wood. It has Dynamic Balance polymer composite drivers, PowerPort bass venting that emphasizes the bass, Acoustic Resonance control that creates a more natural midrange sound, 1-inch Silk/Polymer Dome Tweeters that increase the detail of the smooth response, low viscosity ferro-fluid cooling and heat sink attached to a neodymium magnet, gold-plated 5-way binding posts for secure connections, intert stamped driver baskets, floating anti-diffraction grills, butyl rubber surrounds for greater durability, and magnetic shielding to allow it proximity to electronic devices without fear of distortion.
